<frameset border="0" rows="100,*,50" frameborder="0">
  <frame src="top.htm" scrolling="no" marginwidth="0" marginheight="0" name="Narues">
   <frameset border="0" cols="135,*" frameborder="0">
    <frame src="left.htm" scrolling="no" marginwidth="0" marginheight="0" name="Naru">
    <frame src="right.htm" scrolling="yes" marginwidth="0" marginheight="0" name="AT">
</frameset>
여기서
<frameset border="0" rows="100,*,50" frameborder="0">이부분을보면
                                            ↑
                                    위 아래로 나누었습니다
그리고
<frame src="top.htm" scrolling="no" marginwidth="0" marginheight="0" name="Narues">
↑여기밑에 ↓이걸
<frame src="down.htm" scrolling="no" marginwidth="0" marginheight="0" name="ues">
써주게되면
<frameset border="0" rows="100,*,50" frameborder="0">
  <frame src="top.htm" scrolling="no" marginwidth="0" marginheight="0" name="Narues">
  <frame src="down.htm" scrolling="no" marginwidth="0" marginheight="0" name="ues">
<frameset border="0" cols="135,*" frameborder="0">
    <frame src="left.htm" scrolling="no" marginwidth="0" marginheight="0" name="Naru">
    <frame src="right.htm" scrolling="yes" marginwidth="0" marginheight="0" name="AT">
</frameset>
이렇게 됩니다
그런데 여기서 down프래임을 넣지 않은상태에서는 4분할이 되는데
down프레임을 넣게 되면 화면이 망가집니다 저기를 어떻게 손봐 줘야 할지 몰라 질문합니다
아시는분은 답변 부탁드려요
